BACKGROUND: Double-balloon endoscopy (DBE) utilizes both oral and anal routes. The proper selection of the initial route is important for more rapid management of obscure gastrointestinal bleeding (OGIB). The aim of this retrospective study was to clarify the accuracy of the transit time of video capsule endoscopy (VCE) to the lesion as a predictive indicator for the decision on the initial DBE route. METHODS: Of 172 patients who underwent both DBE and VCE, 65 who were diagnosed with small-intestinal hemorrhagic lesions by both means were enrolled. The relation between VCE transit time to the lesion and the DBE route by which the lesion was discovered was analyzed, distinguishing between 46 complete and 19 incomplete VCEs. RESULTS: Among the 46 patients with a complete VCE, the transit time and position of the lesion were strongly correlated. The best cutoff values for route selection by the VCE transit time from capsule intake and from the duodenal bulb to the lesion, determined using a receiver operating characteristic (ROC) curve, were 60% and 50%, respectively, of the transit time to the cecum. At that point, the accuracy of route selection was 90% and 94%, respectively. Positions shown by VCE for ileal lesions tended to be more proximal than those shown by surgery. In the 19 patients with incomplete VCEs, the best cutoff for transit time was 180 min from the duodenal bulb. CONCLUSIONS: The VCE transit time was useful for determining the route for DBE in OGIB. This parameter was most accurate when the cutoff value for the selection was half of the small-bowel transit time in the complete VCE examination.
